I would love to see a plugin on OMV for NetData, but since there currently is not here is what I did and it works perfectly.
sudo apt-get install zlib1g-dev uuid-dev libmnl-dev gcc make git autoconf autoconf-archive autogen automake pkg-config curl
sudo git clone https://github.com/firehol/netdata.git --depth=1
cd netdata
sudo ./netdata-installer.sh
When completed simply open your servers site and include port 19999 also enable this port within any firewalls configured.
http://server.domain.com:19999
I have not figured out the SSL/https portion as yet, but will update if/when I do.
